- A survey is given to 100 Kitti residents to determine whether Kitti residents want the
road paved all the way to the Madolehnihmw border. At issue is whether the road will
impact the local culture. Kepar, Enipein, Wone, and Rohi are very traditional.
Pavement would make it easier for outsiders to enter this area.

- What is the population?

- What is the sample?

- What is your own opinion: Should roads be built and paved into very traditional areas
such as southern Kitti, Walung, or Rumung?

- What is the population?
- The sibling data from our class is an example of what level of measurement?

- Suppose I want to be sure to collect data from students from all four states in the FSM
at the national campus of the College. I decide to pull random samples consisting of
ten students from each state. What type of sampling is this?

- The age of the students in MS 150 Statistics this term is given by the following data
set:

18, 19, 19, 20, 20, 21, 21, 21, 22, 22, 22, 22, 23, 23, 23, 24, 24, 25, 25, 26

- What is the range for this data?___________________________

- Divide the range into 4 intervals (classes). Record the intervals below.
